High order P-G finite elements for convection-dominated problems

Description

From the error analysis presented in this paper it is shown that de CCAU method derived by Dutra do Carmo and Galeao [3] preserves the same order of approximation obtained with SUPH (cf. Books and Hughes [2]) when advection-diffusion regular solutions are considered, and improves the accuracy of the approximate boundary layer solution when high order interpolating polynomials are used near sharp layers

Abstract (Portuguese)

A partir da analise de erro apresentada neste trabalho mostra-se que o metodo CCAU, desenvolvido por Dutra do Carmo e Galeao [3], preserva a mesma ordem de aproximacao obtida com o metodo SUPG (ver Brooks e Hughes [2]), quando solucoes regulares do problema de difusao-conveccao sao consideradas, e melhora a aproximacao da camada limite quando interpolacoes de ordem superior sao usadas
